GONSlBUClION FOR ROTARY ENERGY-TRANSFORMERS.

Application filed December 12, 1914.

To all whom it may concern lie it known that l, Wilmer. JAcon WonL- nNin-xnu. a citizen of the United States, and a. resident of Norman. in the county of Oleveland and State of Oklahoma, have instator of the energy transformer centrally located within the rotor so that if desired,

the rotor may be driven by applying a tangential force to its periphery from an exter nal source of power instead of by the main shaft.

it further object is to have the main gear of a reduction gcz'ir, through which the transformer may be driven, dir ctly attachable to the rotor of the transformer, thus eliminating the otherwise necessity of extra house and bearings for the main gears of the reduction gear.

Another object of my invention is to have in fluid rotary energy transformers (such as pumps) such a fluid path that only one outside packing box is necessary and this may be either at the discharge or, inlet of said pumps.

Another object of my invention is to have the means whereby in inulti-stage centrifugal pumps, only one packing box is necessary.

l accomplish these and other objects of my invention by the structures disclosed in the accompanying drawing and in which invention, the same characters of reference indi .EltE corresponding parts in all the views shown.

lligure 1 is a side view of a general application of my principle of construction toany energy transformer. Fig. 2 is another view of the general. application shown in Fig. 1. hi 1 being a. View of Fig. 2 from line L-L looking in direction of arrows. Fig. 3 shows a reduced eiid view of the rotor portion of the transformer shown in Fig. 2 to show are attached. Fig. 41 is a cross sectional view of a. centrifugal pump in which the principle is applied and. .lii l is a reduced View of Fig. 4 looking from line .22 in direction of arrows.

Referring first to Figs. 1 and :2, B is a base which supports by column 7) the stator ifi of the transformer centrally within therotor ll. The rotor shaft r fits in the bearing in supported by column 5 'Ilhe shaft r also lits snugly into the central portion of the web construction. r shown in Fig. 3 which in turn fastened tothe rotor. T he rotor is thus suspended about the stator S so that it has running clearance C.

The rotor it may be driven either by the central shaft '11, or by the application of tangential force at an external cirernnference which circumference may be the periphery. In the latter case either a belt or chain might be used as shown by D l)" or the periphery might have a gear r surroiniding and attached to it which mightbe driven by a pinion D through drive shaft 0.. The pinion being supported in bearings I); of columns t1 Referring now to Figs. at and 5 we have again a. base B-SllppOl'tillg" a centrally located. stator S by means of column 3 and the rotor-suspended about it with running clearance U by means of main or central shaft 1'1; through bearing Z2 supported on Column 5 In this case the rotor may also have a bearing support in the st-titling box g and between stages at it where a ring might be fastened. to the tips of the stationary blades 7'. i

As before the rotor might be driven from the central or main shaft r or by the application of tangential force to its periphery as shown by F in Fi x 5. y

In Fig. l, 2' is the fluid inlet. The stuffing box y will be suitably packed so that the fluid will pass from 2' into the pump proper with reduced leakage. As shown. here the fluid path is from Q'- to 1, 2, 3, and l where one stage or cycle has been completed. From here the fluid passes through the second stage starting at 1 and then passing to 2, 3, and l and so on to the outlet. In this representation the blades 6 are fastened to the-rotor It and the blades 3 to the stator Hence the blades 0 rotate giving the fluid an accelerating motion it passes from 1 to 2. At 2 the fluid has reached its niaxiinuin velocity and due to the increase of cross section from 3 to l. the kinetic energy given to the fluid between 1 and 2 iscon erted by means of stationary blades 7' to potential en ergy or pressure in the fluid as it passes from 3 to 4:. Front 1 to the cross section of course decreases.

As here shown the stutling box 9 is at the inlet. By taking blades f from stator and fastening to rotor and by taking bladese from rotor and fastening to statorth'e fluid path will be just reversed so that now a isthe inlet and i the outlet when 9 becomes the stuflin box at discharge.

It s ould now be clearly understood that this invention is not concerned with cross sectional variations: of passages 1-2-3- t 'or with the curvature of the blades e and f,

but has for its foundation the centrally located stator whereby means are afforded 1st, for driving the rotor directly by .the application of a tangentiallyapplied force from an external source of power, and 2nd, for having fluid inlet and discharge passages, in .the energy transformers having fluids as'energy storing mediums,- with axes coincident with that of rotor and extending from and to the same end of rotorv whereb -only one stuifing box is used.

Obviously many changes might be made in the-details of construction or in the combination of the unit ,parts of the construction without departing from the spirit and scope of this invention. For instance, the

unit parts mightbe so arranged as to balance end thrust by having rotors with thrust surf'abes'opposed. I do not, therefore, wish to lipyit my invention to the exact construction or combination of parts shown.

Having described my invention, I claim as new and desire to secureby Letters Patent:
